A MAGNETIC FLAT-IRON.

Application led September 23, 1913. Serial No. 791,429.

T0 all whom t may concern:

Be it known that I, J WALTER Moolen, citizen of the United States, residing at Fort Edward, in the county of Washington and State of New York, have' invented certain new and useful Improvements in Magnetic Flat-Irons, of which the following ,is a specification.

My invention relates to new and useful improvements in liat irons and more par ticularly to irons employedV for pressing heavy goods and garments, the object of my invention being to provide an iron which, although relatively light in construction, maybe made to exert practically any desired degree of pressure upon the garment without etort upon the part of the operator. Y

A further object of vmy invention is to provide a fiat iron including` an electromagnet in its construction, the fiat iron being adapted for use -in connection with a table or ironing board, either formed of iron or similar suitable metal which will be attracted by the magnet or having a sheet or plate of such metal laid upon'for inserted .in the surface of the table or board.

A further object of my invention is to provide a. flat iron construction including an electro-magnet, the coils of the electromagnet being so formed that they may also serve as heating coils to heat the iron and maintain the same the proper tempera-1.

ture.

In this connection a still further object of my invention is to provide an electromagnet the-coils of which are so wound that by the proper manipulation of switches pothe direction of current may be reversed through certain of the coils to vary the attractive force of the magnet without varying its heating eHect.

A still further object of 'my invention is to provide' a flat iron having an electro-l magnet in its construction and also pro vided with separate and independent heating coils in order that the iron may be heated without energizing the electro-magnet if desired. And a still further object of my invention is to provide means whereby the be shut oli? from either the heating coils or said means being so arranged as to in no way interfere with the reversing of the direction of flow of current through certain ing ldformed in' from the electromagnet,

. of the coils of the electro-magnet to vary its attractive powers.

l/Vith these and other vobjects in view, my invention will be more fully described, illustrated in the accompanying drawings and then specifically pointed out in the claims which are attached toand form a part of this application. v

In the accompanying drawings: Figure 1 is a longitudinal vertical sectional view of my improved electric flat iron, parts of the handle being shown in section to disclose certain switches therein, the wiring being omitted for the sake of clearness; Fig. 2 is a view similar to Fig. 1 showing a modified form of flat iron construction; Fig. 3 is a diagrammatic view of the wiring employed in the form of flat iron shown in Fig. l, showing the switches in one position; 4 is aA view similar to that of Fig. 3 showing the switches in reversed 5 is a diagrammatic view of the wiring used 1n connection with the form of fiat iron .shown in Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters. That form of my invention shown in Fig. 1 includes a flat iron body 10 formed of iron and provided in its lower face with a relatively deep channel or groove 11 closely following the contour of the iron and providing a centrally rected core 12. About this core are disposed' the electro-magnet coils 13, 14 and 15, all of these coils being wound in the same direction about the core, as shown in Figs. 3 and 4, and each being independent of the others and each formed from some suitable metal of high resistance wire or the like in order that they may not only act, in conjunction with the core 12 to form the electro-magnet, but also as heating coils for the flat iron. The terminals o these coils pass outwardly through an openthe rear portion of the flat iron body 10. The coils are held -in position within the channel 11 by means of a face plate 1,7 which covers the entire bottom of the flat iron body, forming in eiect the working face of the iron. This plate is constructed of aluminum or some other suitable nonmagnetic metal in order to in no way interfere with the'action of the electroposition; and Fig. p

' while the 'oppositeterminal of said'coil is l, connected by a wire 56 to the other contact 45 ofthe switch 39.

'Such a plate is conventionally In operation the shankmembers 22 and 23 are'- so secured as tocl'ose lthe circuitl between the switch blade' 33 and switch contact 29 under which zcircumstances the 'current will pass through the ywire 46, wire 53, coil 13, wire' 54, one ofthe contact members 40 of the switch 39, wire 55, coil 14, wire 56, the

vother contactmember 40 of theswitch 39,

wire 52, one'o'f' the contact members 40 of 57, coil v15, wire 58, the other contact member 40 of the switch 38, and back through the line Wire 47.- It will therefore be seen that the current will be in the'sam'e direction through all the'coils 13, 14 and.. 15, thus both heating the iron and energizing the magnet. When the iron has become sutliciently heated, the article to be ironedis positioned over the 4plate 59 and.

the"irn then employed in the usual manner.v The `electro-'magnet contained in the body of the iron, 'being energized, stronglyV attracts the plate 59 and therefore causes-.the iron to exertfa ing'iron'ed.' lFor thislreason'the iron itself may the part 'f-'jt e person using theiron. 'It will be-`c"lealf,"h'0wever, that at times such pressure would.' be" too great, particularly when the'ii'onfwas being used in connection great pressure'upon the garment be 'beconstructed'in such amanner asto bel -relatively light a-nd at the employed tol-exert Agreat press'sre upon a4 'garment' 'beinglironed without any el'orton Sametime may be incasso with laces or other delicate -fabrics and for this reason l have provided the switches 38 and 39. Undersuch circumstances the position of both of these switchesV is reversed as shown in F ig. 1t is hardly necessary at this point to trace the entire circuit now formed as it may be readily followed without such description. lt is only necessary therefore to state that when the switches are set the current passes through the coils 13 and 15 in the same direction as'before but.. through the coil 1i in reverse direction. Be-

cause of this the magnetic action will be greatly decreased as the magnetic action of one of the coils will be acting against that of the others and the total magnetic action will be that of one coil alone or one-third the usual action. At the same time inasmuch as the current passes through all the coils the heating effect will in no way be diminished. The relative magnetic effect may of course be varied in diii'erent irons by varying the number of coils and by providing additional switches similar to the switches 38 and 39.

1n some instances it will be found that an electric iron is desirable in which the heating isv accomplishedeither wholly or in part by coils entirely independent of the electro-magnet coils. For that reason there is illustrated a slightly modified form of the ilat iron inFigsQ and 5 of the drawings.

Referring to Fig. 2 of the drawings, it will be seen that the body of the dat iron includes a hollow shell 60 of any suitable or desired shape and size, closed at its lower end by a face plate 61 similar to the face plate 12- and` secured in the same manner. Mounted within the upper portion of this shell is a lining 62 of non-heat conductive material such as asbestos or the like and within this lining, which serves to protect the top of the shell 60 from heat, are heatling coils 63, 6i and 65, these coils being connected in series with each other with the free terminals of the coils extending through perforations 66 and' 67 formed in the rear portion of the wall of. the shell 60. Seated within the shell 60 and immediately below these heating coils, and .resting by its lower face against the plate 61, is a relatively thick plate 68 of iron, this plate being secured in place by screws 69 and being provided in its lower face with an endless channel or groove 70 corresponding to the channel 11 of the iron shown in F ig. 1. The magnetic coils 71, 72, and 73 corresponding to the coils 13, 14: and 15 are seated 1n this the switches 38 and 39. The shank 77 carriesA a switch blade 80 corresponding to the switch blade 33 and the dat iron has a bracket 81 corresponding to the bracket 27 but carrying a pair of oppositely disposed, spacedapart knife contacts 82 and 83 insulated-'from each other by a block 84 of rubber or other suitable material. As clearly shown inthe drawings the switchblade 80 is so proportioned that. it may engage both the contacts 82 and 83 at once when in centrai position ormay be moved to. engage either one separately as preferred.

rl`he wiring of this form of dat iron is identical with that previously described with the exception of the following addition One terminal of the' heating coils is connected by a wire 85 to the contact83 and its opposite terminal connected "by .a wire 86 to that'contact 43 of the switch 78 which is connected to that contact le of the same' switch from which the line ,wire 47 leads.l

rlhe operation of this form of iat ironis yidentical with that previously described if the knife blade 80 is vpositioned in such a vmanner as to engage only the contact 82.

engage only the contact 83 thecurrent will pass from the line wire 46,. through the wire 85, heating coils, wire 86, wire 48 Vand back to the line wire 47, thereby/heating the iron but in norway' energizing the magnet. @n the other hand, if the switch blade 80 is positioned to electrically engage both the contacts 82 and 83 the current will pass' from the line wire e6 through the above described circuit and also through one or the other of the circuits described in connection with the form of iron shown in Fig. 1, whichl of these llatter circuits the current will pass through 'being dependent'upon the position of the switches 7 8 and 79. 1t will' therefore be v seen that with this form'of flat iron the iron Because of this construction a relativelyv light llat iron may be employed with prac, tically little eort and the same results obtained as would be obtained by the employ ment of a very heavy flat iron of the usual type, as the greatest labor in :ironing of course, consists in the force required to. press down upon the iron if it is light, -or to raise andl'owersame out of position if it is heavy. It will of course `be understood that 1 do not wish to in any way limit myself -to the specific' details of constructwn illus-
